Do you have Service Pack 1 installed? What Operating System are you running? Can you run other Spatial Analyst tools? Can the same data be used in Natural Neighbor interpolation? Have you rebooted your machine recently? Thanks Steve

They key to this discussion is the version of ArcGIS. Prior to ArcGIS 10 all the rasters are processed as grids and then converted to your raster format and all feature classes are written to shapefile and then finally converted to your format. So if you are using pre 10, your .tif will be converted to grid prior to RasterToPolygon doing it's thing. In ArcGIS 10 we process the data in it's native format. -Steve

You need an a priori raster as input. Please see the tool's help. To ignore values, set the pixel values (in the input raster) to zero or nodata. Do you have a Geostatistical Analyst license and have you checked it out in ArcMap? Steve

It is not supported for Geostatistical layers. You could send your output to a raster and then reclass the raster and convert that to polygons (or use Filled Contours from http://blogs.esri.com/esri/arcgis/2013/01/17/introducing-the-spatial-analyst-supplemental-tools/). Steve

If you have SP1 installed then NIM079650 is fixed. Open a new blank ArcMap and load only the point feature class and then... Please do the following using the same dataset and field (and using the defaults): 1) create a GA layer using the Wizard 2) create a GA layer using the RBF tool in a model 3) create a GA layer using the the GP RBF tool Right click, each of the GA layers, and choose Properties and then copy the dialog on the Method Summary tab. Are they all the same? -Steve

Does this zero contour form a closed shape and are there any points outside it? SplineWithBarriers will generate predictions in the above case. If you still have questions it will help if you post a graphic. -Steve
